Abstract: LIGHT SENSITIVE FILM COMPOSITION     Abstract of the Invention Light sensitive coating compositions containing a dyestuff, which compositions exhibit improved adhesion to transparent film substrates, are disclosed.  For example, the adhesion between a polyester base film and a light sensitive coating composition containing a light sensitive diazo material, a resinous binder and a dyestuff is improved by additionally incorporating into the composition an effective amount of an adhesion promoter based on a copolyester obtained by the esterification and subsequent polymerization of a lower alkylene glycol with a mixture of terephthalic acid, isophthalic acid, and at least one acyclic dicarboxylic acid.  These coating compositions may be readily removed from the base film by appropriate lithographic developer solutions without substantial residual staining of the film by the dyestuff present in the coating composition.

Abstract: METHOD AND APPARATUS FOR SYNCHRONIZING CHARGING OF DROPLETS        OF A PRESSURIZED CONDUCTIVE LIQUID STREAM                     Abstract of the Disclosure The application of the voltage on a charge electrode to selectively charge droplets of a pressurized conductive ink stream is synchronized with the break off of the droplets from the stream so that the break off occurs in the third quarter of the time period during which the charge voltage is placed on the charge electrode.  To determine in which quarter that break off is occurring, the charge voltage is placed on the charge electrode at the same time fox two adjacent quarters of a cycle during each of the two adjacent cycles in which a disturbance is placed on the stream by drive means such as a transducer, for example, to produce two droplets.  During the next application of the charge voltage on the charge electrode, the charge voltage is applied for the last of the prior two adjacent quarters and the next adjacent quarter during two adjacent droplet producing cycles.  During the third application of the charge voltage on a charge electrode, the voltage is placed on the charge electrode for the last of the prior two adjacent quarters of the second application and the next adjacent quarter during each of two adjacent droplet producing cycles.  The final periodic application results in the charge being placed on the charge electrode during the last of the prior two adjacent quarters of the third application and the next adjacent quarter during each of two adjacent droplet producing cycles.  When the charge voltage is applied to the charge electrode at the time of break off, an optical sensor, which is disposed a predetermined distance downstream from the charge electrode, senses a gap between the two charged droplets because they will have repelled each other.  This enables determination of the location of the break-off point of the stream with respect to when the charge voltage is placed on the charge electrode so that there can be synchronization between when the charge voltage is applied to the charge electrode and the break-off point of the droplets from the stream.

Abstract: METHOD OF FORMING GRADED SHADE BAND ON SUBSTRATE     Abstract of the Disclosure A method of forming a colored shade band having a relatively wide portion of essentially uniform intensity and a relatively narrow boundary portion of graded intensity by spraying a dye composition along a longitudinally extending edge portion of a non-electroconductive substrate such as a glass sheet or a sheet of plastic.  In one embodiment of this invention, the substrate is sprayed to form the graded band and then laminated to a layer of plastic interlayer material to produce a laminated window having a shade band having a desired transverse pattern of graded intensity along a longitudinally extending edge portion thereof.  After the dye composition is applied to a sheet of rigid transparent material to form the band, the coated sheet is assembled with the band facing a layer of interlayer material to form a sandwich to be laminated, the band is transferred from the sheet to the layer during lamination and forms a continuous looking band free of any disturbing features such as mottled appearance and having a boundary along a smooth line and a pattern of intensity similar to that of the colored shade band initially developed.  In another aspect of this invention, the graded band is applied electrostatically to either the interlayer sheet or to the rigid transparent layer under special conditions that results in a gradation of the coating.

Abstract: ABSTRACT OF THE DISCLOSURE         A laser tube mirror alignment fixture for use in adjusting the reflecting mirrors on the ends of a laser tube.  The fixture consists of two flange members which, when welded, form a single convection bellows, and a backing ring in which a number of screws are placed to provide for adjustment of the reflecting mirrors.          The laser reflector is sealed to one of the flanges.          The displacement is achieved by adjusting the screws on the backing ring and creating a differential pressure on the back flange of the bellows which, after adjusting the screws, can be locked tight to ensure no further movement.

Abstract: HyDROCRACKING OF HEAVY OILS/FLY ASH SLURRIES            Abstract of the Disclosure An improved process is described for the hydrocracking of heavy hydrocarbon oil, such as oils extracted from tar sands.  The charge oil in the presence of an excess of hydrogen is passed through a tubular hydrocracking zone, and the effluent emerging from the top of the zone is separated into a gaseous stream containing a wide boiling range material and a liquid stream containing heavy hydro-carbons.  According to the novel feature, the charge stock is in the form of a slurry of heavy hydrocarbon oil and finely divided fly ash or high ash coal fines.  The presence of this ash in the charge stock serves to greatly reduce coke precursors and thereby prevent the formation of carbonaceous deposits in the reaction zone.

A pilot stage is located at the upper end and a plurality of spaced apart intermediate stages are located between the pilot stage and the lower outlet.  Hydrogen and oxygen are fed to the pilot stage for ignition.  Oxygen is fed to a first intermediate stage and hydrogen and oxygen are fed to each of the other intermediate stages for injection into the gas generator.  Excess hydrogen from the pilot stage is burned in the zone of the first intermediate stage and hydrogen and oxygen of each succeeding stage is ignited by the preceeding stage.  Water for cooling purposes also is fed to each intermediate stage.  Downhole valves selectively controllable from the surface are provided for the pilot stage and each of the intermediate stages.  These valves allow the inter-mediate stages to be selectively operated to increase or decrease the BTU output or to vary other characteristics of the output.

Abstract: SELF-CLEANING RAISE BORING HEAD SYSTEM                      Abstract of the Disclosure The body of a raise boring head is produced from a truncated cone.  A variety of efficient and economical methods such as spin-forming, casting, rolling, etc. may be used in producing the truncated cone body.  A multiplicity of rolling cutters positioned in cutter saddles are mounted on the truncated cone body.  The mounting surfaces for the cutter saddles are on a continuous plane.  The continuous plane can be produced on the truncated cone body in one turning operation.  The raise boring head is self-cleaning due to the natural tendency of the cuttings to slide toward the periphery of the truncated cone body surface.          The overall gross weight of the raise boring head is reduced and the strength-to-weight ratio is increased.  The structural rigidity of the raise boring head is improved even though many of the structural components used in prior art raise boring heads have been eliminated.                -1a-
